Similarly Shaped Products

A.
Please send us your part drawing. We can then consider an optimal forming process and/or submit a quote. Feel free to contact us to discuss your requirements even if your design has not been fully decided. Click here to contact us for more information.

A.
It depends on the part. If the part is relatively easy to make using cold forming, it is possible for us to get you a quote in a day or so. If the part is more complex, must be made from a special material, or if there are many manufacturing steps require to produce it, it can take around one or two weeks for us to submit a quote.

A.
Anywhere from three weeks to three months , depending on the prototype geometry and material. Our turnaround time can also vary depending on the availability of a particular process/machine in our factories. One of our sales representatives will notify you of the exact delivery date after your order has been confirmed.

A.
Depending on the size of part and the production machines used, we are capable of producing several hundred million parts per month. Depending on the machine used, we also have the option to build machines in-house to expand our capacity as needed. Please contact us for a production capacity estimate for your product.

A.
We can work with a wide range of metals, including pure iron, carbon steel, stainless steel, copper, brass, aluminum, titanium, Kovar, alloys, and other metals. We can also consider processing special materials provided by the customer. Please contact us to discuss your material requirements.

A.
It is possible to control dimensions down to the μｍ (0.0004in) range, but this depends greatly on the geometry and material of the part in question. Please contact us for questions regarding tolerances and precision.

Quenching is done to increase the hardness of metals. Although quenching increases hardness, it also makes the metal less tough and more brittle, so tempering is often performed after quenching to restore some of the material's toughness.

Annealing

Annealing softens the material and improves material ductility by removing some of the deformation caused by work hardening.

Normalizing

This heat treatment is performed to remove the internal deformation of a product caused during a forming process, to restore the metal structure to its normal state, or to make its crystal grains finer. It also enhances the strength and ductility of metals.

Carburizing

This heat treatment hardens the surface of material. The degree of hardening depends strongly on the amount of carbon, which means that only the surface of a product can be hardened while allowing its internal structure to remain soft. This technique is commonly used to provide products with both wear resistance and toughness properties.

Nitriding

This heat treatment exposes iron or a titanium alloy to a high-temperature nitrogen atmosphere to allow nitrogen to diffuse into the surface of the metal, thereby hardening the surface. The process causes little change in material dimensions and enables the manufacture of products with superior wear resistance.

A.
Yes. We do much of our plating at our subsidiary, Wako Riken. For certain types of plating, we work with external plating companies. We provide zinc, copper, nickel, tin, gold, silver, rhodium, and chromium plating among others. Contact a sales representative for more information.

Iron and steel materials, which are prone to rusting, are commonly plated with zinc to protect against corrosion. After the plating process, the zinc plate is typically coated with chromate to further enhance the corrosion resistance. (Example: trivalent chromate plating)

Chrome plating, which provides a beautiful metallic luster and superior corrosion resistance, is commonly used for decorative applications. It is also used for industrial applications, where its superior lubrication and anti-wear properties contribute significantly to reducing the costs of industrial products.
